This pair of 1961-1962 Chevy Impala 1 & 2-Speed Wiper Transmission Arms is an original used GM part that has been media blasted and primed. We have also replaced any of the swivel bushings that were broken so that it will function smoothly. NOTE: GM made different designs in early 1961 so some of the transmissions are slightly different in the arm lengths. This set is the 2nd or later design and has 27" and 14 3/4" for the RIGHT and LEFT arm length respectively. Please make sure you are selecting the correct length.
